New technologies like the Virochip harness DNA's properties to identify and fight new viruses.
Understanding the immune response is essential to developing safe vaccines for dengue and other diseases.
The SARS epidemic was successfully halted by a global research effort to identify a new virus.
The identification of hundreds of genes involved in the formation and spread of cancer is leading to promising new methods for diagnosis, prevention, and treatment.
An overview of embryonic development, the progressive differentiation of cells, and properties of embryonic stem cells.
In cloning, a cell's genetic machinery is reprogrammed. Can we similarly coax stem cells to become specific cell types?
Dr. Eric Lander takes us on a tour of this remarkable genetic century, describing the rapid advances in DNA sequencing technologies and information science.
To understand life's processes, perturb them. How a process responds to an insult can provide clues about normal function or mimic a specific disease state.
Dr. Lander explores human genetic variation and how it may affect individual susceptibility to certain diseases.
Scientists now have the ability to create millions of new molecules. How do they test whether any of these molecules are useful?
Dr. Page explains how successive inversions and deletions of the Y chromosome during mammalian evolution have reduced it to its present form—small and sparsely populated with genes.
Although tiny in size, the fruit fly has had a major impact on our understanding of circadian rhythms.
Dr. Rosbash discloses how scientists have persuaded Mother Nature to reveal the inner workings of the fruit fly's biological clock.
Dr. Takahashi describes the powerful strategies that he and others have harnessed for understanding biological clocks in mammals.
